用可再生有机电极替代对环境不友好的无机电极是发展大规模储能锂离子电池（LiB）的关键环节。在这里，我们报道了一种基于偶氮苯基和苯并三唑基（BTA）基团的新型锂硼有机电极材料。针对LiBs阳极铜集流体界面易形成Cu-BTA配合物的问题，我们合成了偶氮苯基烷基苯并三唑，并研究了其作为LiBs有机电极材料的电化学行为和反应机理。合成的偶氮苯基烷基苯并三唑在25 mAg- 1 的电流密度下表现出高达365.8 mAhg- 1 的高可逆容量。
The substitution of renewable organic electrodes for environmentally unfriendly inorganic electrodes is a pivotal link in the development of lithium-ion batteries (LiBs) for large-scale energy storage. Here, we report a new type of organic electrode material based on azophenyl and benzotriazolyl (BTA) groups for LiBs. In view of the easy formation of Cu-BTA complexes in the interface of the copper current collector of LiBs anode, we synthesized azophenylalkylbenzotriazoles, and studied their electrochemical behavior and reaction mechanism as organic electrode materials in LiBs. The synthesized azophenylalkylbenzotriazoles showed the high reversible capacity up to 365.8 mAhg- 1 at 25 mAg- 1 of current density.
